excessive battery drain by "android os". dead in 12 hours of idle

When I first got the phone, the first few hours of use seems great.
Then, in the past few days, "android os"is showing up as the main drain, over 50% of battery usage AND my phone is dying in about 12 of just standby. Thanks to android 4.4 and lack of safe root method, I cannot determine what is causing the problem.
Anyone got an idea? Location set to battery saving, location reporting and history off, Wi-Fi scanning off, auto sync on with only contacts calendar and Gmail syncing. Removed most apps. Only known good apps are left

What brand and type of phone do you have?
Did you try duapps battery saver?
Greetz Peter

Did you try an factory reset ?

Towelroot worked on my D415 to root.
Sounds like the device isn't going in to deep sleep when inactive. I usually charge my D415 over night. The past few days my device has been attached to my PC for long periods of time, thus keeping the battery charged. I went to bed the other night with the battery at 100% and woke to the battery still at 100%. In fact, two nights in a row.
I'd try a factory reset. Re-root if necessary. Then carefully uninstall whatever bloatware you don't want. If in doubt, don't uninstall something, ask first. :silly:

I had the exact same problem, did a factory reset and everything went to normal again.
I can go up to 2 full days of battery even with auto-sync and a huge amount of e-mails e calls ( max time in battery was 72h )
If I leave it on standby it basically drains nothing at all (~1% for each 4-5 hours.

I got 2 D415 (tmo US LG L90).
one have this problem, the other doesnt.
One lasts 72 hrs with 1-2 hrs screen on time. The other is having issue. Factory reset didn't help. Factory reset and no account syncing didn't help. It was fine before. Swapped battery between the two to check. didn't help. Everything seems to work fine for both phones it's just that one is having deep sleep issue. Going to try swap it out with TMO.
is towelroot safe? i dont want to jeopardize warranty. (this is my only use of root at the moment. thanks a lot google.)

Towelroot is safe to use for rooting, but rooting voids your warranty.

does the KDZ flashing (in the LG L90 General forum) remove all traces of root so I can effectively bring it back to stock? Tempted to root to fix this problem (thanks google) but afraid of losing warranty.

Wakelocks

Anyone using battery monitoring apps like BBS or GSam, can you share some of your stats here? I'm trying to figure out whether the seemingly massive amount of wakelocks I'm having is normal or not. The biggest problems seem to be coming from the kernel itself. BBS shows a lot of kernel wakelock time, and GSam consistently lists the kernel as the highest drain in its app sucker screen. Also, the Phone app seems to be waking the device a lot since upgrading to .5.51, which wasn't a problem on .3.374.
I've attached some screenshots that illustrate the problem. I'm already using ForceDoze and Greenify, which have been enabled via ADB, and I've restricted background activity and data for the vast majority of my apps. I'm really hoping there's something I can do about this given that it's impossible to use another kernel (LB and none available for this phone anyway). I've software repaired/clean flashed 3 times.
My battery drain is actually not bad at under 4%/hr (combined screen on/off) and about 1%/hour with the screen off overnight. Today I've logged over 4.5 hours SOT in a period of 17 hours and am sitting pretty at 36%. That's better than any phone I've ever used. But I worry that all the wakelocks are using my phone's CPU, raising its temperature, and might contribute to faster battery degradation.
Also, this is with bluetooth off and my Pebble not paired, but battery drain becomes substantially worse with that setup. My idle drain triples with my Pebble connected. I'm trying to troubleshoot one issue at a time and want to nail these wakelocks before moving onto the bluetooth issues.
If your battery stats looked like mine and especially if you figured out how to fix it, please share!

Given that Sony ended .5.51 deployment prematurely and is currently rolling out .8.49, I think you should update to .8.49 (or wait until your region gets the update if you don't have it yet) then recheck if your problem still persists.
Pouring time and resources into a version that Sony is no longer pushing isn't that great of an investment, especially since it's possible that it was fixed in .8.49.

Everything except the phone app using more battery was the same on .374. And I fixed that after force stopping the phone app and rebooting. I've been trying to troubleshoot this for weeks but just upgraded to .5.51 a couple of days ago. I will flash it when it comes out for Customized UK, but I don't think .5.51 is the root of the problem.
(Oh cool, Xperifirm actually shows .8.49 available for Customized UK now. Time for some flashing!)
Edit: I'm seeing the same degree of wakelocks so far on .8.49.

Update: The battery drain from "phone" is actually Android System. There's a bug in Oreo where sometimes Android System is showing as Phone/RCS in the battery stats. Doesn't explain why Android System is using so much battery though.

So I managed to get a lot of my battery drain figured out, but a few things are still bothering me.
1) Google Play Services and Android System and/or Phone (see my last post) are using the Significant Motion Sensor to wake my device constantly.
2) Sony's smart charger (com.sonymobile.smartcharger) is waking my device. I'm assuming this has something to do with Battery Care, which I find to be a useful feature. But why does it need to continue sending alarms to wake up our phones when not plugged in?
I've attached 2 screenshots from Better Battery Stats showing the first issue (Sensors/Play Services and Phone) and 1 showing the second (Alarms/Smart Charger). Note the "wakeup=true" and long times recorded for Significant Motion. This held true when I had my phone sitting face-down on a table for 6+ hours to do battery testing earlier.
Anyone else who uses battery monitoring apps: have you noticed any similar issues?

I'm with you on RCSService being main culpirt for me. No I don't think it's a bug, it actually does use lots of battery. I listen to 3+ hours of bluetooth music a day and when I saw that RCSService was using more power than my bluetooth, then I thought it was time to experiment. So I uninstalled Carrier Service and RCSService and suddenly my battery life jumped by 20%. There was something in the November update to these services that made them go nuts. Several people have noticed a jump in battery usage, but most people, myself included, thought it was down to the new firmware. Uninstalling these 'features' has made no difference to SMS for me, other than I don't get a read confirmation.
I don't know about smart charger, sorry.
Pretty sure the proximity sensor is always on and that must use some power, but I don't know what that would be called in BBS.

Thanks! I should clarify that when I say it's a bug, I believe something is using a lot of battery, but I don't know that it's necessarily Phone/RCS, because it shows up randomly as either that or just Android System. I think it might be something within Android System but being labeled as Phone or RCS. (Edit: Or the other way around; it could be 100% RCS and sometimes shows up as Android System because the phone is part of that umbrella.) I could be wrong but based my judgment on the links I posted above.
That being said, I disabled Carrier Services on your recommendation in the other thread because my carrier doesn't support VoLTE, VoWiFi, or RCS, I've never seen a "delivered" message, and I don't even use the Google Messages app anyway (I use Texra for SMS and keep Messages disabled). So like you, I don't need these services. And I do think there's been an improvement. Might be time to go through the rest of what you recommended via ADB. The only thing that concerns me about doing that is that I'll have to factory reset if I ever switch carriers and want those services, but I guess that's a small price to pay and an unlikely scenario anyway.
The smart charger thing is just weird. It shouldn't need to constantly check whether I'm charging since it kicks in when you plug in. Yesterday I disabled battery care during the day and re-enabled it at night to charge, and I had the best battery life since I've owned the phone: 4.5 hours of SOT over 18 hours off the charger with 30% remaining. I may have to look at idle drain with battery care disabled. I like the idea of battery care, but if it's draining my battery then it just defeats the purpose.
Regarding sensors, BBS has its own category for proximity sensor; this is a separate sensor for significant motion. Somehow Google Play Services and either Phone/RCS or Android System are using that particular sensor all the time. And not just listening to it, but causing lots of wakeups and doing so while the device is sitting on a table all night. I can only deduce that it's somehow seeing motion when there isn't any.

Do you have 'On Body Detection' enabled in smart lock? That would force the phone to affirm if it's moving/stationary regularly and quite often.

I never enabled that from the start, but just checked in case Google did something, and it's still off.
I also checked my app permissions, and the only ones with access to body sensors are Google Play Services and Tasker. None of my active Tasker profiles require the significant motion sensor. One of them does use the orientation sensor to turn the speakerphone on when it's face-up during a call, but I tried disabling that profile and the stats didn't change.
Maybe I have a messed-up accelerometer...do you know of a way to test that? (Edit: Found it in the Support app - my accelerometer, gyroscope, and proximity sensor are fine)
I think I might head to the Sony Mobile forums with the smart charger issue for that matter. It may be a bug that affects all phones with Qnovo features, or maybe they could at least give me an explanation.

Correct me if I'm wrong, but couldn't you just "reinstall" those services via the same adb commands? Where you typed uninstall, just replace with install?

Maybe, but I don't know where I would be installing them from...? Since I don't have a backup of the package. I uninstalled a bunch of stuff via adb before and it didn't return with a dirty reflash. I had to flash userdata. So that's all I'm going by.

I'm not sure of the actual technical mechanics, but I believe uninstalling system apps doesn't actually remove the package from the system image, so you can reinstall them at any time.
I think it's like taking down a sign on a store, the actual store is still there, just all references to it are no longer there, so to the OS it's not listed - "uninstalled".

I gave up. I still have a ton of wakelocks. GSAM shows a bunch of them even when my phone is supposedly dozing. My battery life is OK, not nearly as great as I hoped I'd have with this phone, but it gets me through the day so I've just been living with it. I have noticed better battery on the latest firmware (July patch) than June. I also got rid of the RCS stuff, which helped a bit. And finally I traced a lot of my drain to an app I was using called "hide running in background notification" which the last few firmwares can do natively.
(Edit: Sorry for missing your previous post!)
Edit: I was sadly mistaken about better battery on the July patch. The battery is only better if I'm not on wifi. I posted in the wifi drain thread about it just now.

20% battery drain over night || FIXED || SEPTERMBER 13 2018

Somewhere earlier this year I started getting a 20% overnight battery drain. On a few nights it didn't drain, but its pretty consistent. I have tried everything listed on this forum..This drain is definitely not caused by any standard settings. I am really hoping somebody with insight into Oreo might have something new I could try. I know xda user Digisteve is going to showup and suggest more things, and that is also not going to work.
Things I've tried.
- using root to disable logd. (saw this as a process in BBS) Still drained.
- Disabling auto-sync of all accounts. Still drained.
- Turning on stamina mode at night. Still drained.
- Removed google play store, google play services framework, and all google aps - and replaced with alternative China app store. - Still drained. Not a play services problem.
- Turning off wifi, all wifi scanning, notifications of wifi networks etc. Still drained.
- Turning off mobile data and wifi - no connectivity at all. Still drained.
- Turned of location in all possible device settings,. Still drained.
- Rooted the device with Janjan method/kernal. Still drained.
- Flashed different regions. Including (Taiwan, my region, Malaysia, Germany, Swiss, HK). Still drained.
- Tried firmware verions , 179 , 205, 235, 270
- Deleting 3rd party apps. Still drained.
- Installing Gsam - checking for consuming apps. No apps listed as cause of the drain.
- Installed greenify. Tried as standard, non-rooted with adb permissions, and fully rooted. Still drained.
- Disabling various packages related to 'carrier services', qualcomm and rcs. Still drained.
- Debloated to the point that the phone had no google apps, no Xperia apps and removed tons of other apps, camera bloat, anon data, etc, all removed. Still drained.
- All built in apps replaced with a 3rd party app, including, sms, contacts, email, keyboard. Still drained.
- Installed Linage OS 15.1 Beta 5. Still drained.
- switched from 3G only to LTE only. both drained equally.. though I have worse single with LTE in my area.
I am hoping there is a better solution than throwing the phone away. Because I am pretty much at that point now. I have spent probably well over 120 hours trying to fix this, and I can't. Its at the point where I need to move on to a new device rather than waste more time.... but there are no small devices on the market now, and also no more classic xperia style devices on the market. Sony does not make the executive, classic 'Xperia' style I fell in love with anymore. I don't do round, heavy, huge phones. Very sad.
UPDATE - AUGUST 14
Now running the latest Customized German 270 firmware.
Still draining 20% per night. Check out the screen shots - clear to see I have almost no apps. No process can be seen as a battery hog in both Gsam and BBS. However Gsam screenshot shows evidence of CPU usage.
UPDATE - SEPTEMBER 13 - FOUND THE PROBLEM
Considering almost nobody had my issue, I assumed my phone must be a dud. Late August I bought a second XZ1 compact. The new phone worked for 1 day, and on the second day drained battery at 15% per night idle drain. Previously I had only tested the sim card by switching 3g,4g and disable mobile data, but never actually removing the sim from the phone. Last 2 nights I replaced my old sim with my gf sim of a different carrier. In the morning I had 99% battery remaining. No Drain!
I then downloaded an app these measures signal strength, and turns out where I sleep at night, there is is less reception. Its not noticeable just looking at the standard signal strength on your home screen, you need to check the more detailed strength in decibel millimps /dbm. I can still get good signal in most areas of my house, but the phone is having to use more power to keep the signal good. I can now reproduce the battery drain on demand. If I sleep with the phone near my bed, I get drain. But if I keep the phone in the living room, no drain. I found that connecting to wifi not a factor, since even if you use wifi for data, the phone was still holding open a connection the the cell tower.
This problem took me months, countless hours, and the expense of buying a completely new phone!!! Now I have 2 XZ1 compacts....arg.... but so happy its solved.
The important point is that if testing sim, good signal, or disabling mobile data, changing 3g 4g isn't enough. Your phone is using more power to maintain good signal.
Thank you to everyone who spend time trying to help me, digestive, proflyer, etc. Thank you guys.

At this point, I think it's highly likely you got yourself a lemon. Since you've already rooted the phone, warranty service is out of the question.
It boils down to two options:
1. Pay for a board replacement.
2. Try your luck with a brand new XZ1C. Buy it online so that you'll get the 7 days return perk (some online stores offer 10 days), keep it wrapped in its original packaging, handle with extreme care, and use it normally for a few days before your return window runs out. If you no longer get drains, congrats, and welcome to the club. If not, accept your fate, return it for a full refund, and give up on the XZ1C - understand that you weren't meant for each other and move on.

I had the same issue. Check this thread. Try that and report back.
https://forum.xda-developers.com/xp...ormal-battery-consumption-wifi-t3740495/page3

I know what you feel. I had this too, but mine went away and I only very rarely have this drain. But mine was always on Wifi. With Wifi off = no drain reported... never.
I investigated it for weeks without coming to a conclusion.
If you can, replace the phone with warranty. Worth a try. Right now in my opinion you have a hardware faulty device.
But i would say to wait for android 9. In my opinion it wont take ages to come. It will much likely come this year.

He still has drain even with WIfi Off, so that not the problem.

The only other thing I could suggest is having the battery replaced at a local repair shop. If you got a lemon battery but an otherwise fine phone, that could help.

How about remove your SIM card with wifi on for over night? Do you still experience the drain?

This does indeed sound like an app or a service gets stuck in an awkward way. You indicated in your first post that you use better battery stats, do you mind posting screenshots of the top of the summary, kernel wakelocks and partial wakelocks page (showing keeping awake services) as well as the bottom of the cpu states page (showing deep sleep time) "since unplugged" after a few hours of drain?
I have attached corresponding screenshots here for my xz1c (after more than 24 hours unplugged) as a reference (I have play services enabled and syncing both gmail and contacts and so on, no root though).

That doesnt make too much sense. Test it for at least one week before coming to conclusions.

Try this and let me know if it works
I had exactly the same issue
What i did (now magicaly works)
I did not have too many time so what I did was simple and I got a cheap replacement phone in the meantime
It seems to be beyond everything we tried
I conected the phone to the pc and did the fix with xperia companion, then I realized that everything was working as soon as I started to install the apps the problem came back, I installed a launcher (nova) and use it, drained the battery útil reach zero and fully charge it, then everything was working... Back to normal... I don't know how the issue was solved but hope it works for you
Sorry about my bad english xD

The screenshots from BBS look pretty normal, the GSMBattery shots show issues with Google Play Services, so I'm guessing they were taken at different times. But there's nothing jumps out of the stats that looks out of the ordinary. Have you run the phone in safe mode overnight to see if you get the same drain? I think you may just have a duff battery, no one else has reported this sort of power loss before.
$40 down the repair shop to get a new battery is going to be a whole lot cheaper than a new phone.

Thanks didgetsteve. your probably right.... The GSAM and BBS stats were taken right after each other, maybe a gap of 2 mins. Play Services wasnt the issue though, as I tried my phone google free, and it still drained.

I agree with didgesteve, nothing jumps out by just looking at bbs (I am not familiar with gsam, so I cannot comment so much on that).
Before replacing the battery, I would probably make sure that it is not radio/network related. I have noticed that my phone draws significantly different amount of battery (in deep sleep mode) depending on the mobile network. This is mostly independent on whether mobile data is on or off.
Could you turn on airplane mode for an hour or two and verify that it is not the radio chip that is causing your drain? (If that is the cause, I am not sure if you can do anything about it apart from switching carriers or experimenting with 2g/3g/4g settings, but it might be worth knowing)

I also had the drain that Dean has. But mine wasnt so agressive, I mean, some days it was there draining 30% battery over my sleep time (8hrs) and sometime it just behaved normally draining max 3% over sleep time. But still from time to time the drain come back wich is annoying as I cant let my phone with 30% battery left when im going to sleep, afraid the battery will be dead and the alarm wont wacke me up lol.
On my extensive tests, the drain only happened with wifi, but even deactivating all wifi related process (backups, syncs etc) the drain was sometimes there. Wifi wasnt the culprit with Dean, but on my tests: Wifi On = Sometimes big drain , Wifi Off = never drain.
I never managed to find the culprit of this damn drain and Im a software tester. Gsam did not show anything unusual at all. It was like Deans screenshot.
We discussed about this issue a lot here (https://forum.xda-developers.com/xperia-xz1-compact/help/battery-life-bit-odd-t3688342/page8) but till this day we dont know whats triggering it.
Im curious how the phone will behave on this issue with android P.

@ergoen @Didgesteve . Can you guys comment on my 4th screen shot, the one where you can see the CPU usage. Does anything strike you as odd in that pic? TThe CPU util looks high... it is normal?

i dont see nothing odd there

I'm sorry, but I don't think I have the knowledge to judge that. I would expect CPU usage to be low in deep sleep mode, but since the CPU is mostly sleeping, I guess any requested usage will queue up in a way that might look odd, so what you are seeing might be normal (but again, I don't actually know). I also believe that CPU power consumption is mostly related to the frequency state it is in, so deep sleep should mean low consumption (independent on cpu util %).
As I indicated in my previous post, I would sooner blame the radio chip or the battery than the CPU given your BBS screenshots.

mi drain came back today... some days its there and some days its not...

Bro, Samsung is even worse when it comes to battery drain. Check out linus tech tips vid from a few days ago https://www.youtube.com/watch?v=n46s_iF_IV4&t=324s
My wifes side of the family all have Samsungs.... they are totally ****. The OS is bloated, ugly, laggy despite monster specs huge ram, snap 845, and battery nightmares on brand new phones exactly like in Linus's video. And there is a stupid "BIXBY BUTTON" on the phone which is a total nightmare. if your with Samsung, BIXBY will the with you, following you forever.
In other news, I replaced my Taiwan XZ1 compact with an Australian XZ1 Compact, and my drain is gone. I drained 2% last night.
There are so many build differences with the Taiwan and Australian build of the phone. Bigger microphone holes, slightly different proximity sensor design, and the plastic back is a rough matt black/gray in the AU versions, the TW version was a smoother shiny midnight black with a silver sparkle in the sun. The biggest difference was of course the battery drain.

Odd battery life

Hello,
Since the purchase of my phone XZ1 Compact (G8441), I've been experiencing barely acceptable battery life. This is especially frustrating since I bought this phone having heard that it can last easily 2-3 days, but this is not the case for me (discharging about 4%h on average or 2.5%h with screen off on either wifi or mobile data, with various configurations outside/home/office, i.e. in practice never usable more than a day).
According to *#*#SERVICE#*#*, the battery life is still good (2704 mAh). The issue I am experiencing is most likely due to an unknown software and/or hardware failure leading to lots of wakelocks that prevent the phone from "sleeping"/"dozing" correctly.
I know that MANY users worldwide are experiencing this and Sony never gave an answer to this, according to e.g. the following threads:
https://talk.sonymobile.com/t5/Xper...-drain-after-update-47-1-A-12-235/m-p/1337029
https://talk.sonymobile.com/t5/Xper...-drain-after-47-1-A-12-205-update/m-p/1328053
https://forum.xda-developers.com/xperia-xz1-compact/help/battery-life-bit-odd-t3688342/page8
https://talk.sonymobile.com/t5/Xperia-XZ1-Compact/High-battery-drain/m-p/1326474 https://talk.sonymobile.com/t5/Xper...-drain-after-update-47-1-A-12-270/m-p/1340671 https://talk.sonymobile.com/t5/Xper...pie-battery-drain-CPU-idling-high/m-p/1354891
and many others
In my case the items "NlpWakeLock" and "RILJ_ACK_WL" activate both up to thousands of times every hour. No relevant information could be found about this in the web lookups I've done, and I am not sure this is related to the issue I'm facing. I joined a log of today's better battery stats with a pathetic 1h20 of SOT and 65% discharge, a huge count of wakelocks except when I was listening to music, and an apparent faster discharge with the idle phone than when actually used.
The phone is running the latest downloadable Sony firmware 47.2.A.10.107.
Of course, factory reset was tried with no amelioration and I tried to contact directly Sony which have basically no willingness to help or investigate.
Anyone would have a clue about this?
Thanks,
Alexandre

Do you use Google Now (google assistant) - NlpWakeLock
If not, disable it and see what happens.
This little phone I have for battery life and for banking/authenticator/etc. Not for work. So I have disabled most things I do not need (adb uninstall) - so the battery is quite good on standby.

Thanks for the reply. Unfortunately, as I don't use GoogleNow, the whole Google App is already disabled...
I'll try and do some adb uninstall and will keep you posted

Looking at the bbs stats. The first thing I noticed is that your wifi is on all the time. Try turning it to only when awake and disable the wifi scanning in locatin settings.
RIL wakelocks are on because you have poor signal, it's the number of handhakes your phone does with the local cell tower and if you have bad signal, it gets higher.
Some providers offer home 4g boosters for your home or 'calls over wifi', either of these would reduce your battery usage.

My phone has been flawless (2-3 days on battery when I don't play games) but suddenly it started behaving like described in the original post.
It has 1 day life now and I haven't found the reason for this change. I have removed all recently installed apps, removed all unnecessary apps (including Facebook app), disabled running in background for some (like Messenger), there was no firmware update at that time. Still something is eating up the battery. SmartPanel tool shows that 58% of battery is Unaccounted (next is display and Google Services). I have not done the factory reset yet because I need fully configured phone right now.

Faster battery drain after OTA update to 9.1.0.252 on Huawei P10 VTRL-L29

After updating to 9.1.0.252 I noticed faster battery drain. Did any of you experience the same behavior? I'm thinking to go back to 9.0.1.
Thanks

I feel the same

Don't forget that our device/battery is getting older with every update?.
It might look like new but mine is already 2 years in use.

I noticed faster battery drain on my ltr-09 as well. All is fine now. I noticed when i first upgraded location was turning on alot almost like it was learning when to turn on. Then it levelled out. Example opening google now at first it always turned on my gps now it doesnt. When i was on 9.01 i left my phone on battery saving for gps. You cant on 9.1 and i have seen alot of apps that used to be good with battery saving location now going for full with gps. Big bttery drain. Those were the differences i found. What I believe solved my battery drain was actually my battery getting all screwed up. I had this happen when i would switch roms and my battery stats would get all messed up. I solved it before and solved it this time with my p10 by running the thing right dead. Then pluging it in overnight with it turned off (no fast charging) Then I did it again the next night drained to dead , plug in charge with off ( no supercharging) and my battery life is better again. Hope this helps. EDIT After a few days of testing i still felt the battery was better but battery life still wasnt right. I did a factory installed minimal apps. Battery life was good until play store updated carrier services. I uninstalled updates to carrier services, disabled auto update. Then i actually disabled carrier services completely. Battery seems good now. From what i read carrier services is for next gen texting. Saw online others were having issues with this update.

Wrong, batteries get older with time and charging cycles. Updates have nothing to do with it and if you notice a drain right after one - it has nothing to do with the condition of the battery, it's the update's fault.

updates are huawei's way to convince you to buy a new phone
first they borked the camera, now they are messing with battery

I managed to improve battery life a little bit by disabling apps running in background and disabling unnecessary location permissions for several apps like @bigshowjh said. Like @bigshowjh said I found apps resetting their permission or settings after update. Still the battery life is not like it was before updating with the same usage behavior.

I have ran a couple of days with very good battery life. 11.5 hrs with 62 percent left. Seems like it used to be with Oreo. Overview of all I did was as follows. Clear cache partition, factory reset . Uninstalled Google Chrome (used Firefox instead) set carrier service to factory in apps three dots advanced. Disabled automatic update of carrier services in play store, then in settings apps disabled carrier services completely. Went through and disabled network access to every app that doesn't need it. I don't use Facebook or Facebook Messenger apps. I use them through my browser. Oddly chome on pie is a battery killer as well. I'm very satisfied with proformance of my P10 again.

My GPS is pretty much always off (unless I really need it) and the battery level still goes down by 9% during the night. It used to be 3-4%.
I cannot find carrier service anywhere.
In my case I can't see power hungry apps in the stats, standby process uses the most energy.

Settings, apps, apps again, select three dots in upper right, select show system processes. You will find it there it's a little hidden lol.

Still no carrier services for Play Store.
